PAUL NATHAN, OF NEW YORK, N.'Y., ASSIGNOR TO HIMSELF AND HORATIO J.BREWER, or sAME PLACE.

ADJ USTAB LE GAG E.

SIECIFIGATION forming part of Letters Patent No. 416,737, dated December10. 1889. Application filed August 24, 1888. Serial No. 283,659. (Nomodel.)

To all whom it may concern.-

Be it known that I, PAUL NATHAN, of the city, county, and State of NewYork, have invented a new and useful Improvement in Adjustable Gages, ofwhich the following is a full, true, and exact description, referencebeing had to the accompanying drawings.

My invention relates to an improved gage specially adapted to machinesfor cutting paper or similar purposes, in which the sheets of thematerial to be out are held under a clamp, and in which it is desired tocut a width narrower than the clamp from the compressed edges of saidmaterial. In these machines a gage is employed to measure the width ofthe strip to be cut from the compressed layers, which gage, moving upona scale, determines the exact width so cut off; but since the edge ofthe material must be under the clamp the gage cannot rest under saidclamp without interfering with the action of the clamp; and I thereforehave devised a removable gage which can be moved beneath the clamp, andsubsequently withdrawn therefrom before the clamp is depressed, therebygaging the material to be cut, while at the same time it passes outsideof the traverse of the clamp.

My invention will be readily understood from the accompanying drawings,in which- Figure 1 represents a plan view of the ad justable part of thegage, showing the gage open; Fig. 2, an end view of the same; Fig. 3, aView corresponding to Fig. 1, showing the gage closed; Fig. 4, avertical section through the machine, showing the clamp elevated and thegage arranged to gage the material to be cut; and Fig. 5, a plan View ofthe same, with part of themechanism removed. l

A represents the table upon which the gage slides and the material to becut rests. B is the scale, upon the same. The gage itself is shown at O,with the adjustable part D E attached thereto by set-screws F. The gageitself may be fed bythe feeding-screw G, and the clamp H set by thescrew J.

The knife K is operated by any suitable mechanism.

L represents the pile of sheets to be cut.

The adjustable gage D E is constructed on the general principle of aparallel ruler having pivoted arms M, which, by preference, haveright-angled projections N, which, when the gage is opened, as shown inFig. 1, bear against the strips 0 P of the gage. These strips orsurfaces 0 P may be cut away, as shown, to allow of the passage of thearms M when the gage is closed, as shown in Fig. 3. A clip B may beemployed to hold the gage open, as shown in Fig. 1.

The operation of my machine can now be understood. The clamp H beingraised and the gageE thrown forward to the proper point, as shown inFig. 4, the paper L is moved up against it, and the gage isthenwithdrawn out of the way of the clamp, which is then forced down tohold the paper in position preparatory to the cutting by the ,knife K.Again the gage is thrown forward and the sheets fed to it. The arms Mdetermine the fact that the gage is moved forward exactly the samedistance on each occasion. It is obvious, of course, that in buildingnew machines the main gage C may be dispensed with and the adjustablegage only used; but my apparatus can be applied to existing machines inthe manner shown.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination, in a gage for cuttingmachines, of two parallel barsprovided with stops, and armspivotally secured to the bars and adaptedto bear against said 1 stops. and limitthe movement of said bars,substantially as described.

2. The combination, in a gage for cuttingmachines, of two parallel bars,arms pivotally secured thereto, and a lock for securing said bars inposition, substantially as described.

3. The adjustable gage" having parts 0 P,

to this specification in the presence of two sub- I
